Wireguardstatistics in luci doesn't show any data

Installed wireguard succesfully and it’s working (apart from two bugs, this thread and another one which may be a configuration problem) quite good.
One problem I have is, that the wireguardstatistics module in luci under the “status” menuentry doesn’t show any data about connected endpoints, here’s a screenshot:

How does this module work and where does it get its data? Maybe there’s something missing, which is needed for the data collection.

I already mentioned this here.
Please search the forum before opening new threads.

Did you open a bugreport (gitlab or mail) already?

It is a bug in TOS3.x and I doubt that it will be fixed in that trunk. It does work in TOS4.x beta1. The wg status can be queried via ssh cmd alternatively.
